In a move to keep their defense unit shored-up and intact, the Phoenix Coyotes signed David Schlemko to a two-year extension worth $2.38 million, the club announced Monday afternoon. Schlemko, 25, was originally signed as an undrafted free agent by the franchise on July 19, 2007 and has since spent time both at the professional level and several other minor league teams that the Coyotes also oversee, including the AHL’s Portland Pirates and San Antonio Rampage and the CHL’s Arizona Sundogs, with whom he won a title with in 2008.
